Jon Hamm SLAMMS... Justin BieberTurns out that Don Draper is not a Belieber. Who'd have thought it?! Hamm branded the pop troublemaker a "s**thead" for his recent questionable behavior in an interview with Men's Fitness this week, saying: "You're like, 'What the f**k, man? What are you doing? Why?'

"You see people in the world and you're like, 'Do you know how a washing machine works? Do you know how to wash a dish?' Life skills are something we're missing… just s**t you needed to learn in life."

In probably Hamm's most notorious slamm, the actor said of the privileged pair: "Stupidity is certainly celebrated. Being a f**king idiot is certainly a valuable commodity in this culture because you're rewarded significantly."

Jon Hamm SLAMMS... Reality starsAnother slamm in the same vein as his Kardashian takedown, this. If you dream of rubbing shoulders with Binky & co in Made in Chelsea, or are already planning your first glossy mag shoot in the queue at Big Brother auditions, Jon Hamm has a problem with you.

"If that's all you want, you can just be on The Bachelor or The Real Housewives or whatever show just wants oversized personalities, ridiculous behavior and zero dignity," he said. "When you try to learn how to act, you approach it with respect. But if you just want to be famous... that's not much different than porn."

A triple slamm that almost seems engineered to make teenage girls across the globe cry! "All I can say is that I don't get Miley Cyrus, I don't get Katy Perry, I don't get One Direction. I don't get why that's a thing," he told Shortlist when asked about young headline-grabbing stars.

"The culture we live in is one that needs something to talk about all the time. Seriously, it's the dumbest thing in the world."

Jon Hamm SLAMMS... People who make fun of his penisIt's become apparent thanks to a number of pap shots and Tumblr pages that the Mad Men star is in possession of "impressive anatomy". But rather than take pride in what God gave him, Jon is a bit annoyed with all the playground giggling.

"Would you want people walking up to you and pointing at your d**k?" he asked. "The fact that I'm painted as this exhibitionist is a little annoying. It's become a meme."

Speaking of penises, if you have one and you don't hold the door open for a lady, then Jon Hamm thinks you're even worse than the sexist, chauvinistic characters on Mad Men.

"There's a cordialness that men had when dealing with the opposite sex, even when they were being blatantly sexist," he said. "It's a weird conundrum. But that's been replaced with men treating women like absolute garbage and not even being polite about it, which is too bad."

Jon Hamm SLAMMS... BillionairesRemember when we had to wait aaaages before Mad Men's fifth season finally landed in 2012? Well, according to Jon Hamm, it was money-grabbing TV bosses that caused the hold up.

"These decisions get made... at a much higher pay grade than I'm allowed to partake in," he said. "I've described it thusly, and I've gotten in trouble, so I'll do it again the same way - when billionaires fight, it takes a lot longer to... settle."

"There are certainly moments when I haven't liked what Don has done, some of the things he's done are reprehensible," he said. "I think at the end of the day he is a coward... when presented with difficulty, he tends to run away."
